Question

I am right now working on an app which works as a book-stack,where user can read books of their choice,now what i am doing is,displaying the html pages that i’ve made,in a web-view in my application.
Now this application works only if the user has full time internet connection on his phone.
What exactly i want is when they first open the application,they would need internet connection and then the app should be able to download that page and store it in local database so the user can read it later on without having any internet connect.
So is there any possible way to download the html page and store it in local database so user can use the app even if he is not connected to internet?
I can post my code here if needed be.
Any smallest tip or help would be really great as i am stuck here since long now:(

EDIT 1:

So i successfully downloaded the HTLM page from the website,but now the problem that i am facing is,that i cannot see any of the images of the downloaded html. What can be a proper solution for this?

Answer 1

Here what’s the mean of “Local Database“?

Preferred way is download your pages in either Internal Storage(/<data/data/<application_package_name>) (by default on non rooted device is private to your application) or on External Storage(public access). Then refer the pages from that storage area when user device has not a internet connection (offline mode).

Update: 1

To store those pages, you can use simple File read/write operation in Android.

For example:

String FILENAME = "hello_file";
String string = "hello world!";

FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();

This example store file hello_file in your application’s internal storage directory.

Update: 2 Download Web-Content

HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet("http://www.xxxx.com");
HttpResponse response = httpClient.execute(httpGet, localContext);
String result = "";

BufferedReader reader = new BufferedReader(
    new InputStreamReader(
      response.getEntity().getContent()
    )
  );

String line = null;
while ((line = reader.readLine()) != null){
  result += line + "\n";
}

// Now you have the whole HTML loaded on the result variable

So write result variable in File, using my update 1 code. Simple.. 🙂

Don’t forget to add these two permission in your android application’s manifest file.

  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
  <uses-permission android:name="android.permission.INTERNET"></uses-permission>
